How many sigma bonds and pi bonds are in a carbon-carbon double bond?
Answer and explanation
Correct answer: D. One sigma bond and one pi bond
- Step 1: Every double bond has one sigma bond from direct overlap. Step 2. The second bond is a pi bond from sideways overlap. Answer: one sigma and one pi. Why not the others: A carbon-carbon double bond consists of one axial sigma bond from overlapping sp2 hybrid orbitals and one lateral pi bond from unhybridized p-orbitals.
